A similar condition to craniopagus parasiticus is polycephaly, the condition of having more than one functioning head. There are many documented occurrences of this in the animal kingdom, although in most human cases we refer to the condition as conjoined twins. One recent case was that of Syafitri, born in Indonesia in 2006. These conjoined twins were given just one name by their parents who insisted that they were, in fact, one baby girl since they had only one heart and shared a body. It would have been impossible for doctors to separate the conjoined twins, and Syafitri died of unknown causes just two weeks after she was born.
